How to encrypt PDF files on Linux Server using Java PDF Toolkit (jpdfkit.jar)? |

Hello, I would like to encrypt my PDF files on the Linux server, our workflow works by following steps,

1. Convert smart form (this is the form in SAP) to OTF format.
2. Convert OTF to PDF and encrypt PDF files on Linux Server.
3. Send PDF file by email.

this is our process. I need encrypt pdf at step 2. I need to encrypt without downloading the file.
